Mashable reported that Randi Zuckerberg posted a photo on Facebook, which she believed would only be seen by her friends, of her family, including Mark Zuckerberg, reacting to the social network’s new Poke iOS application.

The photo was then posted to Twitter by VoxMedia Director of Marketing and Projects Callie Schweitzer, and BuzzFeed captured the following Twitter exchange between Randi Zuckerberg and Schweitzer before it was deleted:

Randi Zuckerberg: @cschweitz: Not sure where you got this photo. I posted it only to friends on FB. You reposting it on Twitter is way uncool.

Schweitzer: @randizuckerberg I’m just your subscriber and this was top of my newsfeed. Genuinely sorry but it came up in my feed and seemed public.
